It works with all the streams I've happened to try. I will be taking a close look at the iostreams library proposal. In the course of implementing the serialization library I've had to become much more familiar with locales, facets, codecvt, element types, EOF, etc than I wanted to. Oh - and that fact that different versions of the standard library have myriad minor quirks that have to be considered. This was necessary in order to avoid dependence on the stream in the wrong way. I'm very interested in this but have come to the conclusion that there might be more here than meets the eye. - Of course that's why we have the review process. Robert Ramey

boost::optional - Include none.hpp instead of none_t.hpp?
by Schalk_Cronje＠NAI.com 02 Jun '04

02 Jun '04

Was it intentional to include none_t.hpp instead of none.hpp in boost/optional.hpp? Otherwise it seems that the user must resort to including boost/detail/none.hpp

Hello In files: libs/thread/src/mutex.cpp libs/thread/src/recursive_mutex.cpp libs/thread/src/mutex.inl boost/thread/mutex.hpp boost/thread/recursive_mutex.hpp there is CR+CR+LF used as line separator. Also, in recursive_mutex constructor if defined(BOOST_HAS_WINTHREADS) m_critical_section should be initialized before m_count (it's compiler warning) Regards, Janusz

New utility at boost/detail/allocator.hpp
by Joaquín Mª López Muñoz 02 Jun '04

02 Jun '04

Hi all, As requested by some at the mailing list, I've migrated allocator.hpp from boost/multi_index/detail/ to boost/detail/ (with some obvious namespace changes.) I'd like to remark the following: * This allocator.hpp has nothing to do with a header of the same name who was sitting there and John Maddock kindly removed a few days ago. * The header provides some utilities to do rebinding of allocators even in MSVC++ 6.0 (where the std syntax for rebind does not work), and also exposes a tiny wrapper over defective std::allocators, providing some missing template members to make them std compliant. * I'd appreciate if those of you who were originally interested in using this header can do some sanity checks to make sure everything works for you (it does for Boost.MultiIndex). We have some room for improvements and fixes until Boost 1.32 is branched for release. Best, Joaquín M López Muñoz Telefónica, Investigación y Desarrollo

Test failure for basic_cstring_test

port of library to vacpp (item 2)
by Toon Knapen 02 Jun '04

02 Jun '04

I stumble on another problem when trying to compile the test library with IBM/VisualAge (vacpp). Apparantly vacpp has a problem on lines 97,98 and 99 of boost/test/detail/basic_cstring/basic_cstring.hpp. Basically the problem is this: this file declares a class template < class CharT > class basic_string { public: typedef basic_string<CharT> self_type ; self_type& trim_left(self_type exclusions = self_type() ) ; // line 97 } ; If I now remove the default initializer, vacpp does not choke anymore (same situation on lines 98 and 99). I tried to isolate this problem in small test but in a small test vacpp seems to deal with the situation just fine. Thus AFAICT this is a compiler-bug but would anyone mind if I remove the default initializers or just remove them in the vacpp compilation to get one step closer to running the regression tests on vacpp again.

RE: [boost] Re: iostreams library review

02 Jun '04

"""""""" > what is the fate of this library? Thanks for your interest! The previous version available at http://www.xmission.com/~turkanis/iostreams/. """""""""" I downloaded the library from the yahoo link you mentioned in the review request. When trying to use 'filtered_stream' I ran into some compilation issues (RedHat 9, g++ 3.3) and before looking into it I wanted to know the review status. Knowing that the library is in the review pipeline I will give it another try. Some time ago I developed simple iostream adapter 'library' that allows to wrap IO device (sockets, pipes, etc) in std::[i,o,io]stream that is very similar to your sink/source technique. One difference is that the adapter is a template class parameterized by the source/sink types. Since your library offers this functionality (plus much more) I am very pleased it will become part of boost soon. """""""""" A quick look your page is very interesting. (looks very cool) I was thinking (also) along the same lines for some work I am currently doing, but you beat me to it. Question, have you tried to combine the streaming with boost serialization?
